v0.2.3 — Loading Screen Fix

• Fixed a bug where the world-loading screen could hang at "Almost ready..." forever when entering a world. The screen now recovers automatically and returns you to the world atlas with a "try again" prompt if the world fails to load.
• Trying to enter a world right after a failed load no longer gets stuck on "World is loading — please wait." You can
retry immediately.
• Minor under-the-hood cleanup.
